Wheel Apparatus has been involved with the ASTM Standardization Process for over 30 Optional Test Kits are available for either ASTM B or G testing. EPI Materials Testing group does custom wear testing and three standardized wear tests for their clients, ASTM G65, G, and B ASTM Methods ASTM G65 – 04 Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus ASTM G – 02() Standard.

By having control of the drum speed, much lower abradant mass flow rates can be achieved than in the ASTM G 65 method. There is g1005 a need for a reliable and convenient approach to the study of abrasive wear properties. This standard is not included in any packages. Standards Subsctiption may be the perfect solution. Both manually controlled and servo controlled pneumatic loading are available.
ASTM G – 16 – Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests
Abrasive wear of industrial materials handling plant e. A touch—screen digital controller provides the user interface. In all cases the abrasive used is rounded quartz grain sand. For wet tests, water is introduced on to the wheel surface, just behind the chute.
The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials.
The ASTM test pieces are relatively large and therefore expensive to prepare out of typical satm surfacing materials.
Materials of higher abrasion resistance will have a lower volume loss. Including aetm abradant feed system and peristaltic pump for alternative horizontal loading configuration. Precision abradant feed system and peristaltic pump for alternative horizontal loading configuration. Already Subscribed to this document. The feed rate satm varied by adjusting the speed of the slotted drum. The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters: We have no document adtm for this standard.
Download the Machine Leaflet. Smaller quantities are desirable if non-standard abradants are to be used. The particle loading is a very crucial parameter for a given abradant as this controls whether the particle cuts or is crushed in the contact. The machine is floor standing with test assemblies mounted zstm a back-plate and abradant discharged downwards into a hopper.
The value of the test method lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Any abradant that does not pass through the contact may be collected separately and therefore the quantity of abradant actually passing the test block may be determined.
It would be preferable to be able to run with smaller samples or even to run multiple tests on one sample, thus reducing the cost per test. Link to Active This link will always route to the current Active version of the standard. In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards.
The absolute wear rate and asgm ranking of materials are greatly influenced by the following parameters:.
Abradant properties, namely hardness and crushing strength 6. This is not possible in the ASTM configuration. You may delete a document from your Alert Profile at any time. The values given in parentheses are for information only.

Particle loading may be controlled over a wide range by adjusting the mass flow and the normal load on the test block. Your Alert Profile lists the documents that will be monitored. Historical Version s – view previous versions of standard. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
This means that fully wet tests can be carried out, with g150 mass flow of abradant still satm. Test rollers not included. It is the responsibility of the user of this standard to establish asttm safety and health practices and determine the applicability of regulatory limitations prior to use.
Imbeni V Hutchings I. Particle speed or cutting speed 4. The wear resistance of a material cannot be predicted reliably from simple properties such as bulk hardness, elastic modulus or tensile strength. Proceed to Checkout Continue Shopping. The wet rubber and steel wheel astk use a large volume of slurry containing 1. If the document is revised or amended, you will be notified by email.
A number of standard methods have been developed with the aim of producing test data that will reproducibly rank materials under a specified set of conditions.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. Please first log in with a verified email before subscribing to alerts.
The specimen arm may also include a satm gauge transducer to measure the dynamic friction.
With variable speed drive adtm and manually controlled pneumatic loading with precision regulator, force transducer and digital display. To provide analogue voltage friction force signal for data logger or chart recorder input.
